EYEG LASS -G UARD.

SPECIFICATION forming part of Letters Patent No. 740,721, dated October6, 1903.

Application filed November 12, 1902. Serial Ilo. 130,946. (No model.)

To all whom it may concern:

Beit'kn'own that I, JOEL C. Wants, a citizen of the United States,residing at Southbridge, in the county of Worcester and State ofMassachusetts, have invented certain new and useful ImprovementsinEyeglass-Guards, of which the following is a specification.

My invention relates to eyeglasses, and particularly to the nose-guardof an eyeglass.

The object of my invention is to provide an improved nose-guard ofsimple construction and efiective operation which is'preferably made outof one piece of metal and formed into the desired shape.

In order to make the nose-guard effective and capable of holding theeyeglass in position on the nose of the wearer, it is particularlydesirable to have as large a bearing-surface as possible to engage thenose and to make the bearing-surface of such a construction that it willnot mark or disfigure the nose.

In my improved nose-gu ard I pro vide a large bearin -surface withoutany opening or perforation therein, but with a depressed or cuppedcentral portion which acts to form a suction on the nose and in this wayholds the eyeglasses in position with less spring-pressure than isordinarily required. The portion around the cupped portion is preferablyroughened.

My invention consists in certain novel features of construction of mynose guard, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a rear view of a pair ofeyeglasses having noseguards embodying my improvements. Fig. 2 is afront perspective View of one of the nose-guards shown in Fig. 1,showing also a portion of the lens, lens-mounting,and spring. Fig. 3 isa cross= section on line 3 3, Fig. 1,

looking in the direction of arrow (1, same figure. Fig. 4 is a sectionalview of one of the lenses and the lens-mounting shown in Fig. 1 andshows one end of the spring and the upper end of the nose-guard attachedto the lens-mounting. Fig. 5 is a central section through the free endof the nose-guard shown in Fig. 3 detached, taken at a point indicatedby line 5 5, Fig. 3, looking in the direction of arrow 1), same figure.Fig. 6 showsadetached nose-guard embodying a modified construction ofthe nose-guard shown in the previous figures, and Fig. 7 shows anothermodified construction of my noseguard. Figs. 2 to 7, inclusive, areshown on an enlarged scale.

In the accompanying drawings, 1 represents the lenses; 2, thelens-mountings, having the posts 3 thereon, to the ends of which aresecured by a screw 4 the end of the spring 5 and the upper end of thenose-guard 6.

All of the above parts except the nose-guard 6 may be of any ordinaryand well-known construction.

The nose-guard 6 is preferably made out of one piece of sheet metal outin the desired form and preferably bent into U shape, as shown in Figs.1, 2, and 3, and having the attaching end 6" of less width, with a holetherethrough, adapted to fit into the recessed end of the post 3, to besecured therein by the screw 4, as shown in Fig. 4.. The free end 6" ofthe nose -guard 6 is preferably of oval shape and about twice the widthof the end 6. The intermediate portion of the guard 6, between the ends6 and 6", forms a loop (W. The free end 6,whioh engages the nose, has adepressed or cupped portion 6, which is preferably about one-half thesize of the end 6. The edge or hearing portion of the end 6, around thecupped portion 6 is preferably slightly bent, curved, or roundedoutwardly or toward the lens, as shown in Fig. 5, and is preferablyprovided with a roughened or grooved surface, as shown.

The action of the cupped portion 6 on the end 6 is to make a suction onthe skin of the nose, against which the end (5 bears, and thus cause thenose-guard to firmly engage the nose and hold the eyeglasses in positionwith'a lighter spring than is ordinarily required, thus making lesspressure on the nose of the wearer and causing the eyeglasses to be morecomfortable than eyeglasses with the ordinary style of nose-guards. Thecurved or rounded edge on the end 6 prevents the edge of the end fromscratching or irritating the skin of the nose of the wearer.

I have shown in Figs. 6 and 7 modified constructions of my nose-guardshown in Figs. 1, 2, and 3.

Instead of making the noseguard of U shape, with the attaching end andthe free or hearing end in two different planes, I may make it fiat,with the attaching end and the bearing end in the same plane, as shownin Figs. 6 and 7 and as is customary in the ordinary offset nose-guard.

In Fig. 6 the nose-guard 7 has the attaching end or arm 7, with a holetherethrough, and the free or bearing end or arm 7", one end of which isenlarged and has the'recessed or cup portion 7 corresponding to thecupped portion 6 in the end 6 of the nose-guard 6.

In Fig. 7 the nose-guard 8 corresponds to the nose-guard 7, shown inFig. 6, but has two recessed or cupped portions 8, instead of one, onthe bearing surface or arm 8.

It will be understood that the details of construction of my improvednose-guard may be varied somewhat, if desired.

Having thus described my invention,what I JOEL O. \VELLS.
